Can you get pregnant after your period just went off the day before ?

Conception timing: Getting pregnant depends on many factors. While most people do not get pregnant at this point in their menstrual cycle, it can happen.

Yes: Pregnancy has been documented from exposure on any day of a woman's cycle including during menses. This is rare around the period but seen with those having irregular ovulation/cycle patterns. There are no "safe days" so a form of BC is important if you want to avoid pregnancy.
